' WALL GAS HEATER Filed Jan. 10, 1938 Patented May 23, 1939 UNITED STATES PATENT OFFICE 9 Claims.

My invention relates to gas heaters something of the type shown and described in my Patent No. 2,130,086 which is a stand lamp type of heater, movable from one place to another in a room as a stand lamp is moved.

My present invention is a combination radiant and air circulating heater adapted and designed to be placed upon the wall and supported at the desired height to give the best results in the room in which the heater is mounted. It combines an effective radiant heater element, with gas burner so related thereto that the best combustion is secured and direct radiationdownward'ly and outwardly on to the floor, where the heat is desired.

In addition, I have provision for effective air circulation upwardly through and outwardly from said heater, so that the best circulating results are secured.

In order to explain my invention more in detail,

I have shown on the accompanying sheet of drawings, one preferred embodiment of the same, which I will now describe:

Figure 1 is a top plan View looking down upon a gas wall heater on the wall, shown in section,

and embodying my invention;

Figure 2 is a front elevation of the same;

Figure 3 is a bottom plan view thereof;

Figure 4 is a vertical sectional view taken on line 4 --4 of Fig. 2;

Figure 5 is a sectional view taken on line 55 of Fig. 4; and

Figure 6 is a detail sectional view taken on line 6-6 of Fig. 5.

Referring now more in detail to the drawing, I

designates a wall, which may be of any construction, and to which is shown nailed a supporting sheet metal strip or bar 2, with its upper portion bent outwardly, as at 2, to have hooked thereover the supporting part of the heater, said supporting strip 2 also having two struck out lips, as 3, 3, to prevent the accidental upward movement of the heater on the wall sufiiciently to unhook or dislodge it from the wall.

The present embodiment of the invention comprises a supporting body sheet 4, having its opposite edges bent rearwardly at right angles as at 4, and its top edge bent backwardly and downwardly, as at 5, with an opening 6 in its front upper portion, for a purpose hereinafter again 5 referred to.

A back sheet I also has its opposite sides bent forwardly at an angle, to fit into the bent edges of the body sheet 4, forming an air space between said sheets, as seen at 8, for the upward circulation of air to the opening 6.

Secured to said supporting body sheet 4, in front, is another sheet member 9 having its opposite sides bent to an angle, to form a channel portion, as 9', for the upward circulation of air therethrough. These interfitting members can be seen in the bottom plan view in Fig. 3, as well as in Fig. 4.

Mounted through the upper part of the supporting body sheet 4, is a horizontally extending top member l0, having its rear edge extended 10 through the opening 6, and bolted to the back sheet 1, as with an angle member l I.

Mounted also on the front of the body member 4, is another horizontally extending shelf-like member 12, having its rear edge secured, as by 15 bolts I2 to the member 4, just below the opening 6.

Mounted on the front of the front member 9 is another horizontally extending shelf-like member l3, having its rear edge secured, as by bolts l3, to the top of the member 9, with its rear edge out out around the top of the member 9 to form an opening at M, for the outlet of air passing upwardly in the member 9, at 9.

The three horizontal members l0, l2 and I3 are 25 spaced by spacers as I5, 15, held on brackets l6,

IE, on a drum member ll, secured to the upper part of the front sheet or member 9, as at its inturned edges, to which it is bolted or secured, as at n', ll. 30

Outside of said drum I1, and spaced therefrom, is another drum or half drum, as the other is, designated l8, which is always cool, and serves as a shield against possible contact with any hot part of the heater. 35

It will be noted that the three horizontal shelflike portions or members are successively receding in their rounded front edges, as l3, l2 and [0, being sufliciently back from the outermost drum l8 to be free of possible contact. The top mem- 49 bers Ill and I2, have the upwardly flowing air through the back vertical passageways 8 and 9, against their undersides as it passes upwardly thereto and thence outwardly and upwardly around the outer edges of said members l0 and I2. 45

Secured to front of the outer front member 9, as by brackets, as 19, is a concaved sheet metal member 20, supported on its outer edge on the brackets l6, I6, and having its outer edged turned downwardly, as at 20, to receive and hold therein the upper edges of radiant clay refractory segments 2|, 2|, the lower edges of which rest upon a sheet metal member 22, secured to the upper member 20 by means of bolts 23. Thus the clay radiant elements are supported at an angle of 55 substantially thirty degrees so as to radiant heat downwardly and outwardly in an effective manner.

Mounted upon the lower edge of said front member 9, is a connecting member or casting 24, to which is attached a gas supply pipe 25, and connected with the top of which is a Venturi casting 26, upon which is mounted a semi-circular burner head 21, directly under the lower and smaller end of the radiant elements, substantially as illustrated.

Supported under the radiant elements 2|, within the inner drum H, is a screen 28, designed to catch any falling ash or anything which might possibly drop thereupon and to prevent anything from being inserted upwardly thereunder. The

- screen is supported by its frame members 28' in the drum I! and member 9, in any desired manner.

Thus I have provided a very practical and efficient wall heater which is adapted to be hung upon a wall at a convenient height for the purpose of radiating heat downwardly and outwardly and for causing a more eifective circulation of air through and around said heater, and while I have shown one practical embodiment of the invention, with gas used as the heating medium, I am aware that changes can be made therein without departing from the spirit of the invention, and I do not, therefore, limit the invention to the details of construction and arrangement shown, except as I may be limited by the hereto appended claims.
